To all whom it may concern:

Be it known that I, ADoLPHE. PiiIBIL, a citizen of the Empire of Austria, residing in Marseille, France, have invented certain and combinations of throu h a lubricating device constructed in accor ance'with the invention. Fig.2 is an new and useful Improvements in Automatic Lubricat ors, of which the following is a specification. v

This invention relates to lubricators; and the object of the invention is to provide'a'dee vice of this kind in which the feed of the lubricant is produced and automatically regulated by the movement or vibration of the machine or part to be lubricated.

A'further object of the invention is to furnish a lubricating device which takes the form of an attachment for the part to be lubricated and which may be very readily applied to and removedfrom such part.

, With these ends in view the invention consists in the novel features of construction described and claimed.

In: the accompanying drawing, in which the same parts are denoted bythe same :reference characters throughout the several views, Figure '1 is a vertical centralsection elevation of the device. Fig.3'and earere- 'spectively a vertical- -central section and an elevation of a modified form of the device.

Fig. 5 is atrans'verse section through a j our-- rial-bearing, showing the improved. lubricator applied thereto." Fig. 6 is an elevae tion, partly in section, of a connecting-rod bearing, showing the device applied thereto; and Fig. 7 is a longitudinal section through-a journal-bearing, showing-a modified arrange ment of the lubricator. 4

r The lubricator comprises a tube.1,.having a laterally 7 enlarged cup shaped end 1 threaded u on its periphery. Said cupshaped end terms a seat fora valve 2, preferably having the form of a ball and this valve controls the passage of the lubricant through the bore of the tube 11 Thevalve 2 is seated loosely. uponthecup-shaped upper end of the tube 1, .but is maintained in association with said cup-shaped end by amp 3, prefer ably of hemisphericalform, having at its 4 lower inner part screw-threads which engage By means of this" I ma be controlled. The cap.3 is provided with a p urality of perforations in order to admit.

parts to be hereinafter I nicating with'said pocket an d the journal, of fa .ball withirisaid'pocket the lubricant to the interior of the same and to the tube when the ball-valve is moved away from the mouth of the same.

Figs; 3 and 4 illustrate a modified construetion in which the amplitude of movement of Y the-balhval'ye 2 is regulated by an adjusting-- screw 4, threaded through the upper central portion of the cap 3 and having at its lower end a 'curved'foot 5, adapted to restrain the IneJVement of the ball-valve away from the tu e; i

- Fig. 5 shows. the 'im roved lubricator as applied in practice to a caring. The tube-1 V is countersunk in the journal-boxfi and communicates with a passage leading to the jour-I nal. "The cap Sand ball 2' of the lubricator-- are arranged within a pocket 7 formed in'the upper part'of the journal-box 6.] In practice thepocket Z jis fill'ed. with oil or other lubricant, and the movement or vibr'ation-ofthe j ournal-box causes the ball 2 to be moved upand down on. its seat and to--con'seq uently' permit the ingress of the lubricantwhich has passed. through the erforations ofthe cap,

into the tube,frorn w enoe it is conducted to .the' journal. "Thus themovement or vibration ofthe pai't to belubricated is factitivein bringing about the feed ofthe lubricant in the proper amount.
